TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Application filed January 8, 1887. Serial No. 223,770.

To all whom it may concern.-

Be it known that I, WALTER S. FRAZIER, residing at Aurora, in the countyof Kane and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Two-Wheeled Vehicles, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a plan showing the shafts made in two parts. Fig. 2 is a plan showing a pole, a portion of the shafts being removed. Fig. 3 is a detail, being a side view of a portion of a shaft, showing the same made in two parts and united by couplings. Fig. 4 is a vertical longitudinal section through the parts shown in Fig. 3. Fig. 5 is an under side view of the showing the top of one end of the cross-bar which is attached to the pole with a connecting-iron secured thereto. Fig. 7 is a section at line a: of Fig. 6. showing the axle. Fig. 9 isa section at line 00' of Fig. 8. Fig. 10 is a modification showing an axle substantially the same as that shown in Fig. 8, with a tie-bar made integral with the upper portion of the axle. Fig. 11 is a section at line at of Fig. 10.

The objects of my invention are to provide an arched axle made of wood which shall be light, stiff, and strong, so that the weight of the driver and the motion of thevehicle will spring it as little as possible; to provide a tiethe axle; to provide a two-wheeled vehicle with shafts made in two parts, so that a portion of each shaft can be removed and a pole of peculiar construction be used, which I accomplish as illustrated in the drawings, and as hereinafter described. Those things which I claim as new will be set forth in the claims.

In the drawings, A represents my improved axle. It is made of three pieces of wood, a central piece, a, Figs. 8 and 9, an upper piece, 6, and a lower piece, 0, the center piece, a, being mortised or let into the upper and lower pieces, be. As shown, the center piece, a, is made of a single piece; but it might be made of two or more vertical pieces secured together, and the grain of the several pieces running in somewhat different directions would Fig. 8 is an elevation Patent No. 361,685, dated April 26, 1887.

make this piece somewhat stifferthan if made in a single piece. The pieces b 0 are to be bent in the usual manner. The center piece, a, does notextend quite to the extreme ends of the axle, and the piec s b c are brought together and made of a proper form to receive the usual irons.

In Fig. 10 I have shown an axle made as before described, except that the axle in this figure is provided with a tie-bar, B, which is made integral with the upper piece, b, of the axle proper. The piece I) and the tie-bar B can be readily formed from a single piece by cutting out so much as may be necessary from a single solid piece and bending the piece b into proper form. The ends of this tie-bar are designed to be secured to the tops of the shafts. Each shaft is made of two pieces.

GQrepresent the rear portions of the shafts, and D D represent the remaining portions of the shafts.

E is a piece of metal, preferably made of wrought-steel. This piece E is of peculiar construction, consisting .of what may be termed a plate, from which projects downward a piece, d, near the rear end, and from each side there is also a downward-projecting flange, e.

ff are ears, which, as shown, are made integral with E. This piece E is secured to the front end of the rear portion, 0, of the shaft by means of a bolt, 9, at the rear end of E, and by means of a clip, h, the ends of theclip passing through the ears f. At the forward end of this metal piece E there is a recess, 1', on each side.

F is another piece of metal, preferably made of wrought-steelof the form shown in the drawings. It has a plate portion,j, with which is connected a piece, 70, which extends rearward, and the rear end is provided with a screwthread, and is adapted to enter a hole in the downward projection, d. This piece it fits in between the downward flanges e e. As shown, this metal piece F is secured to the portion D of'the shaft by means of two bolts, 21, and a clip, m, the ends of which clip pass through cars a on F.

When the two parts of the shaft are together, as shown in Fig. 3, the end of passes through the hole in d, and the rear-end of that which I have called the plate portion of F enters the recesses i, and a single nut, 0, will hold the two parts of the shaft together. The form of the irons E F is such that when the two parts of the shaft are together, as shown in Fig. 8,

there will be sufficient strength, practically equal to the strength of an undivided shaft.

G, Fig. 2, is the main portionof a pole.

H is a cross-bar secured to G. To each end of this cross-bar an iron, 12, is bolted, the rear end of which is screw-threaded and adapted to pass through one of the projections d. The rear end of the pole G may enter a socket secured to the cross-bar I, which socket is not shown in the drawings.

The front portions, D D, of the shafts can be easily removed by removing the nuts 0, and then the pole can be substituted for the removed portions of the shafts by passing the ends of the ironsp intothe holes in the downward projection d, and securing them by nuts 0.

I thus provide a very strong high-arched axle made of wood. I also provide such arched axle with a suitable tie-bar made integral with the upper portion of the axle. I also providea two-wheeled vehicle from which the forward portions of the shafts can be easily removed and apole be substituted therefor. If the central portion, a, of the axle be made from two vertical pieces, a thin strip of metal of proper form might be placed between such pieces to give additional strength. Such a piece of metal might be placed on the outside of the central piece, a; but I do not think this 'metal piece necessary.

of three pieces, a b c, in combination with a tie-bar, B, made integral with the upper piece, I), of the'axle, substantially as and for the purpose specified.

3. The combination, with a vehicle shaft made in two detachable parts, 0 D, of a plate, E, secured to the under side ofthe part 0, and having a downward projection, d, and depending lateral flanges e e, and a plate, F, secured to the under side of the part D, and projecting rearward to engage the projection d and flanges e e, substantially as described.

, 4. The combination, 'with a vehicle-shaft made in two detachable parts, 0 D, of the plate E, secured to one of said parts, and provided with projection 01, flanges e e, and earsff, the plate F,secured to the other part and provided with projection is and cars it n, and the bolts 9 Z, clips h m, and nut 0', substantially as described.

5. In a vehicleshaft madein two detachable parts, the rear part, 0, having secured to its under side a plate, E, provided with a depending perforated projection, d, and depending lateral flanges e 6, whereby it is adapted to be engaged either with the projecting portion of i a plate secured to the front part of the shaft or tions d, of the pole G, having a cross-bar, H,

provided at each end with a rearward projection, 10, adapted to engage said flanges e, and

projections d, substantially as described.
